This harder ore took longer to grind and crush than the anticipated softer rock, a process that can demand threetofour times more electricity to process than a softer ore body. Responding to this obstacle, the mine's energy consumption jumped from 14 GWh/month in 2013 to 26 GWh/month in 2015, significantly increasing the mine's HFO consumption to generate the required power.

A Method for Making Transparent Hard RockLike Material ...
At present, a similar material most commonly used in the similarity model experiment of rock blasting is cement mortar. However, it is not transparent, which leads to the problem that the cracks in the model made of cement mortar after the test cannot be observed directly. Therefore, a kind of transparent hard rocklike material that can replace the existing model material to solve the above ...
